This is a process producing an artificial joint for abraded joint surfaces. The joint is produced of metal and polyethylene. The main purpose of the artificial joint is to provide a capability of painless movement. Knee prosthesis was used for the first time in 1968. This method became a much more succesful way of treatment today, thanks to surgical technics, used materials and improvements in designing periods.
Some of the patients may not recover despite the treatments like relaxation, drugs, physical treatments, using baston and intra-articular injections. In this cases, total knee prosthesis treatment is feasible for the patients who have knee aches, are banned from doing dailiy activites like jogging or coming up a ladder and are heavily ruined on joint cartilage.
